WHEELED GUN-QARBIAGE.

Specification of Letters Patent Patented Aug. 24 :1909.

T0 all whom Lt Mag concem; 7

Be it known that I, HEINRICH KANONEN- BERG, a subject of the Emperor of Germany,

and a resident of 99 Rellinghauserstrasse, Essen-on-the-Ruhr, Germany, have invented certain new and useful Improvements in Wheeled Gun-Carriages, of Whichjthe fol lowing is a specification. i y

The present inve ntion relates to the type of wheeled gun-carriages WhiCh is provided with a fixeol spade and with a spacle shiftable into ancl out of working position andjin which the shiftable spacle, when it is in it s working position', lies against the fixecl spade.

The object of the invention is to provide a gun-carriage of this type in which the fixed spade is capable 0f constantly relieving the shiftable spadeof strain in an eflective manner when the shiftable spade is in the Working position.

In accordance with the present invention this object is attained by provicling means f0r pressing the shiftable spade when in the Working position, against the spade which is fixed on the trail of the' carriage.

One embodiment 0f the invention 'is shown in the accompanying drawings by way 0f example. v

Figure 1 is a siole view of the trail of a wheeled gun-carriage. Fig. 2 is a top view of Fig. l, partly m section 011 lin e 22, Fig. l; Figs. 3'130 5"are sicle views corresponding to that shown in Fig. 1 but showing difi"erent positions of some 0f the parts; Fig. 6 is-a section online 66 Fig. l, 100king from the left; Fig. 7 is a sectionon line 77 Fig. 2, looking from below; Fig. 8 is the same section as1 {chat shown in Fig. 7, the parts being in the position shown in Fig. 4:,

and Fig. 9 is the same sec tion as that shown in Fig. 7, the parts beinggin the position shown in F ig. 5. Figs. 6 to 9 are on an enlargecl scale.

A indicatesthe spadewhich is fixed 0n the gun-trail B and Which is adapted for use 0n hard grounol and C C indicates the sh i ftable spade which is adaptecl for use 011 soft grqund. The spade C C which mainly comsists of the spade-blade G and' a press-plate C is provided with two parallel arms 0 and 0 which,by means of 'eyes c, are swingingly connected 130 trunni0ns 'd (Fi g. 2) on trail B. The common axis of the. trunnions Z}, that is the axis of rotation 01: the spacle C C is eccentrically lo'cated relatively to the axis 0f rotation of the holt D (see especially Figs. 7 t0 9) so. that a turning movement of the holt D Will eflect a displacement of the axis of rotation of the spade.

As s h0wn in Fig. 2 the holt D is composed of tW0 parts and 011 one end 0f the holt is rigidly secured an operating lever D which is provided with a handle d. The lever D which is macle from elastic material, such as steel, is providecl with a lateral projection d for which a plurality of notches c are provided in a later'al projection- 011 the adjacent arm o'--. The projection 0 011 the arm cprojects into the path of movemenc of the projection d* 0n the lever D t0 such an extent that a comparatively great amount of lateral bencling 0f the lever l) is required to bring che projection d into o1 out of en .gagement with 0ne of the notches c.

, The arms 0 and 0 of the spade O C are providecl with noses 0 Which, when the spade is in its working position shown in Fig. l, engage in corresponding notches b provided in the side Walls of the gun-trail. In this position of the spade C C the spadeblade O contacts With the entire opposing surface 0f the blade of the fixed spade A a bolt D which :ls rotatably mounted in the \Vhen the spade C C is iIi the position v this figure, ancl also in Figs. 8 and 9 the axis of the l:runnionsd is projected in the point d" and the plane which contains the axis of the holt D and is parallel to the supporting plane of the carriage, is projccted in the straight line It W111 be seen from Fig. 7 that, when the the point (Z is located near its 1eft dead point relatively to the line 0ca2 and ehe arrangement -is selected in such a manner that, When the lever D is brought intc engagement with one of the notches c which is located nearer to the press-plate C the point approaches the adjacent dead poinc without, howeve1', passin'g beyond the same.

Vhen the lever l) assumes the angular position shown in Fig.4 the j ooint d is in its intermediate position asshown in Fig. 8. When the lever D is trned frotn the posi tion shown in Fig. 1 (o the angular position shown in Fig. 4 the spade C C must therefore move 110 the right and the arrangement is selected in such a ma1iner that t-he projection's 0 of the arms 0 und 0 cf ehe spade C C then move so f'ar out of the notches 12 that they are free t0 swing past the lower Wall of the notch@s b as shown in Fig. 4.

VVhen the spende C C is in the position shoWn in Fig. 3 and the lever D is brought into engagement with one of the notches c in the arm 0 the leverD asswnes approximate1y the same angu1ar osition as that shown in Fig. 4; the point 01 is therefore in this instance located near its intermecliate 130sition shown in Fig. 8. In this positiorl of the parts a Swinging movement of the spade C C about the trunnions (Z al cann0t take place. When the 1ever D is turned fi0m che position shown in Fig. 3 to the angular osition shown in Fig. 5, in Which, as shown in Fig. 9, the point 0Z is in its right dead point relatively to the 1ine mm, 'the spade O C must 1110x e t0 the right and the zirrangement is se1ected in such a manner that the cutting edge 0 of the Spade thcn passes so far out cf the notches 12 that the spao1e is free t0 be swung in the direction of the arrow y, as shown in Fig. 5.

During the travel of the gun, o1 when the spade A alone is used, the shiftable spade C CF assumes the position shown in Fig. 3 in which it, Whi1e secured against swinging movenrient, tests With its cutting edge 0 in the notches 6 of the supports b In this Gase the lever D is adjusted in such a manner that its' projction d is in engagement With one of the notches 0 in the arm 0 T0 shift the spende C C inco the working position the gumtfail is raised and, after the 1ver D has been bent laterally to such an extent that its projection cZ* has passed out 0f engagement with the appurtenant notch c", the lever D is turned in the direcfi on 0f the arrow y t0 ehe position shown in Fig. 5. Due to the eccentric arrangement cf the trunnio'i1s d the spad6 O C is thereby moved so far 'to the right that its cutting cdg'e 0 ca n Swing out of' the not'ches b The Spade C. C i's thereu1aon swuhg in the direction 0f the arrow 2 until it lies With the central pa1t of its press-plate C against the lower wall 0f the trai1 and simultaneously therewith t-he lever D is swung in the direction cf the arrow y until it reaches the position shown in Fig. 4. In this position of the lever D ehe noses 0 011 the arms 0 and 0 a1e located atthe same elevation as the notdhes Z) without however engaging in the notches. Thereupon the lever D is turned in the direction opposite t0 the arrow 1 The spade C C is thereby moved to the 1eft so that the noses 0 011 the arms 0 und 0 are pushed into the notches b A short time bef01c the1ever D has reached the1ositi'on shown in Fig. 1 the blade G of the spade C C comes in'toabutment with the spade A. The leVer D can then only be turhed farther 011 thc application cf comparatively great foree. The turning 015 the lever D is continued until its projection d snaps into that notch c in the projection c which is farthest from thc press-plate C As the axis cf the trunnions d in this position 0f the lever D is I'1ear its dead point a togglelever action takes place during the last pztrt of the turning movement of the lever D and this action causes the spade C C to be pressed with great force against the spade A. The spade C C is then in an effective manner coupled to the spade A. Consequehtly the spadc C C is t0 a great extent relieved of strain during firing.

If the parts become worn or change their position due to shocks 01' sonne other cause und the pressure thereby becomes insuflicient With which the spade C C is pressed against the spac1e A in the osition cf the 1ever D shoWn in Fig. l, this fact can easi1y be compensated for by bringing the projec- 131011 cl of the 1emr D into engagement with one of the notches c nearer to the pressp1ate C i'm being readily understood that 7 this Will cause an incre'ase in the pressure. In this manner it is possible to constantly relieve the shiftable spade of strain by n 1ea1ns 0f the spade A Which is fixed on the trai It W111 readily be understood from the foregoing and need not be explained in what manner the shiftable spade C C is brought from the working osition tothe posit1on shown in Fig. 3.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:

l. A wheeled gun-carriage having a,- fixed spade and a spade shiftable into andout of working position, and means for pressing the shiftable spzlde against the fixed spade When the shiftable spadc is in its working position.

2, A wheled gun-carriage having a fixed spa de and a second spade adapted t0 be working position in Which it lies against the fixed spade, and means f0l pressing the second spade against the fixed spade when the second spade is in its working position.

3. A wheeled gun-carriage having a fixed spade and a second spade adapted to be shifted from an ineffective position to a working position in which it lies against the fixed spade, and means for pressing the second spade against the fixed spade when the second spade is in its working position, said second spade having its blade contacting Wiih the entire opposing surface of the b1ade of the fixed spade when the second. spade is in its working osition.
